In order to reduce marine shaft-rate electric field influence and the exposure rate of the ship,the mechanism of the electric field is analyzed in this paper, along with the principle of the active compen-sation system. Specifically, the electrical properties are studied based on the analysis of the mechanism ofshaft-rate electric field of the ship. The ship shaft-rate electric field suppression is proposed according tothe compensated negative potential. The framework and function framework of the system are designed. Theweak signal monitoring and processing technology of ship shaft is investigated, and the judgment and con-trol technology of the system is studied. The driving and power output module of the negative potential is de-signed, where the simulation results show that the ship shaft-rate electric field can be suppressed effective-ly with the proposed system, and the stealth property of the ship is simultaneously enhanced.
